11 Modem Reset
11.1 Modem-Watchdog
In EM260/GSM with
Wavecom-Adapterboard
starting from V1.2, a Watchdog function is
implemented ex-works. The watchdog controls
the modem function and resets the modem in the
case of a failure.
The watchdog is active if the jumper
”JP7“
(“ Watchdog “) is in the position “ enabled “.
11.2 Cyclical modem reset via output 4 of the EK260
After activating the modem reset function the modem is restarted once a day via output 4 of the
volume corrector. Time and duration of the modem reset are defined by the time window 2 of the
EK260. If time window 2 is used to control the modem reset, it can no longer be used as a call
acceptance window. In this case, call acceptance is exclusively defined by time window 1.
)
In EM260 with Wavecom adapter board starting from V1.2, a watchdog function (refer
to chapter 11.1) is implemented ex-works. The watchdog controls the modem function
and resets it in the case of a failure.
The presence of the watchdog makes the cyclical modem reset via output 4 of the EK260
unnecessary. Output 4 of the EK260 can still be used for call acceptance.
)
The modem reset function should be activated only if necessary (if manually operated
modem resets have repeatedly been necessary to ensure the accessibility of the
modem)!
Ex-works the modem reset function is not activated!
To activate the modem reset function, it is necessary to send a special parameter file to the
EK260 and to modify the wiring between the EM260 and the EK260 (see below).
Before activating the modem reset function, the following conditions must be fulfilled:
ƒ
The version number of the Wavecom-Integra-Adapter board (ID no. 73018344) inside the
EM260 must be 1.1 or higher.
ƒ
On a Wavecom-Integra-Adapterboard V1.1 the soldering pad LF7 must be short-circuited,
e.g. by a 0 Ohm resistor.
ƒ
In the case of an EK260 V2.2x, the modem reset function cannot be activated when a SIM
card with an active PIN is in use.
